IMPROVED BINDER. FOR PAINT-BRUSHES.

titte .tlgttnle nicht it im time tetten ttttt mit making @mit nxt tige time Be it known that I, J'. F. CANNING, of Boston, in the county ofSuiolk, and Commonwealth of Massachusetts, have invented a new and useful Improvement in Paint-Brushes, of which the following is a "full description, reference being had to the accompanying drawings, for an explanation thereof. I The ordinary method of constructing such brushes is to secure the bristles to the handle by 'means of a ferrule oi' twine or wire, as represented in Figure 1 oi' the accompanying drawings. While this narrow ferrule holds and binds the bristles'with'sutlcient strength, it at the same. time admits ot their full use and wear at their -entire length; but to make such use practical when the brush is new, it is customary to wind the brush with twine, or similar material, till it is covered as far up as 'my binder covers it, as represented in Figure 2. This process presents too great play of the bristles, and in the ordinary use of the brush, asv the bristles weer down, the twine is unwound to a corresponding degree, thus enabling` it to be used till thc bristles are worn 'lo prepare a binder oi' twine in this way isa troublesome and laborious operation, and theaction of" the spirits and components ofthe paint so aiects the twine by use, that it is found to be constantly breaking and unwinding, and is thus a constant source of trouble and-delay to the operator. To obviatc this diieulty, several different binders have been introduced to general use, but from their expense, or some equally valid objection, they have been generallyabandoned, and the old method of winding with twine resumed.

' On June 20, A. D. 1854, Letters Patent, No. 11,129, were issued to John S. Martin for an improvement in painters brushes, which improvement consisted of an adjustable elastic tubular binder, and which -said invention and Letters Patent were duly assigned to me by deed of assignment, dated June 1, 1867, and duly recorded in the 'Patent Oiice; This invention proved by use of little practical value, from the fact that the paint so affected the material of which the binder was made'as to destroy its consistency and elasticity; and no elastic material could or can be found that will resist such action of the paint. My present invention is free from such objection, and from all the objections made to the binders hitherto in use, inasmuch as it is so cheaply constructed as hardly to increase the cost of the brush. Itis easily adjusted, and conformable'to the wear of the brush, and so prepared as. successfully to resist the action of the paint or material in which it is used.

To enable others skilled in the art to make and use my invention, I will ndw describe its' construction and operation. In the accompanying drawingsv Figure 1 is a paint-brush constructed in the ordinary way, and without 'the binder-A being the handle, B the ferrule, and C the bristles, extending beyond the fcrrule'.

Figure 2 is the brush with my binder attached, it being marked D, and fastened by the seam d, as hereinafter described. y

Figure 3 represents the shape of the binder as cut from the cloth or canvas, and before it is attac-lied to the brush, a being the top-side, which, when tittached, is `towards the handle ofthe brush. i

Out of thick cotton or linen cloth, or ordinary canvas, I cut the binder, in the shape shown in iig. 3; the object of the spaces 1 2 3 4 being to avoid unnecessary'bulk over the ferrule, to cause it better toailhere tothe ferrule, andto allow the'lower eide to compress the bristles more closely. I then wind thebiuder tightly around the brush, the top edge a being placed even with the top of the ferrule, and then stitch it together in such a manner that the seam, (represented in iig. 2,) will not rip if astitch is broken or cut.- After it is thus firmly xed around the brush, I saturate the binder thoroughly with-a prepmation composcdpof alcohol, shellac, and mastic, mixed in the following proportions: To one gallon oi' alcohol I add six poundsof shcllac and halt `a pound of mastic. This, when dried, renders the binder impervious .to the action ot' paint and varnish', gives it the desirable consistency, and causes it to adhere more closely to thcfi'errule of the brush.

It is obvious that as the bristles wear down hyuse, the binder can be Aeasily cut oit in a corresponding degree, itbeing so stitched as n'ot to rip. Having now described my invention, what I claim as new, and desire to secure by Letters Pntcnnis- The binder D, as made and applied, when coated with a mixture composed of' shellac and mastic dissolved in alcohol, in the manner and for the purposes set forth.
